We show the first THz emission of a graphene based plasmonic antenna structure. Furthermore we present the minimum material requirements for an operational graphene antenna in terms of chemical potential µc and relaxation time t.

We present a three-dimensional continuum model for layered crystalline materials made out of weakly interacting two-dimensional crystalline sheets. We specialize the model to multilayer graphene materials, including ...

El artículo caracteriza a nivel estructural, morfológico y térmico tres muestras distintas de óxido de grafeno comerciales (AGO, EGO y CGO) obtenidas mediante el método Hummers, las cuales han sido posteriormente reducidas ...

Harvesting energy from ubiquitous moisture is attracting growing interest for directly powering electronic devices. However, it is still challenging to fabricate high-performing moisture-electric generators (MEGs) with ...

[ANGLÈS] This project presents a study for both optic and electronic properties of graphene and possible variations of different physical magnitudes that are produced in a material when a single layer of graphene is deposited ...

In this article, the interaction between a methane molecule and a graphene plane in liquid water has been characterized employing DFT-based free energy Molecular Dynamics calculations. This system represents a good model ...

Blisters induced by gas trapped in the interstitial space between supported graphene and the substrate are commonly observed. These blisters are often quasi-spherical with a circular rim, but polygonal blisters are also ...

Measuring the electrical surface resistance of 2D materials without contact can provide a method for obtaining their intrinsic characterisation. The aim of this paper is to show that a rutile dielectric resonator (RDR) can ...

Engineering the doping level in graphene nanostructures to yield controlled and intense localized surface plasmon resonance (LSPR) is fundamental for their practical use in applications such as molecular sensing for point ...
